An older Caerphilly
Census 2011 data also show a change in the local population's average age.
Between the last two censuses, the median age of Caerphilly increased by three years, from 37 to 40 years.
This industrial area had a slightly lower average age than Torfaen (one of the most statistically similar areas to Caerphilly based on ONS area classifications) (41 years of age) and remained slightly younger than the average local authority area across Wales (41 years of age).
The fall in age was because of an increase of almost 4,900 people between the ages of 60 and 69 years, while the population between 30 and 39 years decreased by just under 3,000.
About 12% of people in Caerphilly are aged between 60 and 69 years
